Transmission Method, Transmission Circuit and Transmission System

1. A transmission method for transmitting transmission data via a plurality of lines, comprising: transmitting, through each line, data that has one rising or falling transition of an amplitude of the data in each clock cycle of a clock and that carries a 1- or greater bit value, using a phase from an edge of said clock to said transition in amplitude of the data; and transmitting data by selecting one line for transmitting said data from said plurality of lines in accordance with a 1- or greater bit value of a second data to be transmitted for each of a same number of consecutive clock cycles of said clock as a number of said lines.

2. The transmission method according to claim 1 , wherein said phases include two or more phases and said lines include three or more lines.
